The train was empty and no one was harmed in the derailment, which happened around 7pm on Wednesday and lead to major disruptions on the commuter line that connects the French capital with Charles de Gaulle airport in the north and the Orly airport in the south as well as the cities northern and southern suburbs.

Ce soir le #RERB a déraillé à Denfert-Rochereau. Heureusement il n’y a pas de blessé. L’investissement pour cette ligne ne peut plus attendre ! Les politiques d’austérité budgétaires mènent au pire. pic.twitter.com/sw6xK6LfHl

Buses were put in place between the stations that were completely closed – Denfert-Rochereau and Laplace to the south of Paris – but they were crowded and difficult to access, French media reported.
Après le déraillement d'un train, le trafic est fortement perturbé sur le RER B ce jeudi. Des bus de substitution ont été mis en place, mais ils sont pris d'assaut par les voyageurs ? pic.twitter.com/WMAHQu81vK

On the rest of the line trains were running on a reduced service, with roughly half of the trains running as normal, according to operators.
Responding to frustrated users who could not get to work the RATP network wrote in a tweet that alternative transportation bus were “complicated” at the moment, but that they were looking for an alternative solution.
@aileean4eva Bonjour, oui c'est possible mais attention le trafic est fortement perturbé pour effectuer ce trajet. La situation dans les bus est également compliquée, un renfort est en cours. ^b
